Homework: 5.1 Systems of Linear Equations
Klio2033 [76]

Answer:

\mathrm{The\:solutions\:to\:the\:system\:of\:equations\:are:}

x=8,\:y=5

Step-by-step explanation:

Given the system of linear equations

7x-y=51

x+3y=23

solving by the elimination method

\begin{bmatrix}7x-y=51\\ x+3y=23\end{bmatrix}

\mathrm{Multiply\:}x+3y=23\mathrm{\:by\:}7\:\mathrm{:}\:\quad \:7x+21y=161

\begin{bmatrix}7x-y=51\\ 7x+21y=161\end{bmatrix}

7x+21y=161

-

\underline{7x-y=51}

22y=110

so

\begin{bmatrix}7x-y=51\\ 22y=110\end{bmatrix}

now solving for y

22y=110

\mathrm{Divide\:both\:sides\:by\:}22

\frac{22y}{22}=\frac{110}{22}

y=5

\mathrm{For\:}7x-y=51\mathrm{\:plug\:in\:}y=5

7x-y=51

7x-5=5

7x=56

\mathrm{Divide\:both\:sides\:by\:}7

\frac{7x}{7}=\frac{56}{7}

x=8

\mathrm{The\:solutions\:to\:the\:system\:of\:equations\:are:}

x=8,\:y=5

A triangular banner has an area of 5ft squared. The height is 3 ft more than the base. Find the base and the
Korolek [52]

Answer: base a=2ft

               height hₐ=5ft

Step-by-step explanation:

use equation for area of triengle

A=a*hₐ/2

hₐ-height of tringle

a-base of triangle

hₐ=a+3

A=a(a+3)/2

2A=a²+3a

A=5ft

2*5=a²+3a

a²+3a-10=0

a=(-3±√9+40)/2

a=(-3±7)/2

a=-5ft

a=2 ft

hₐ=2+3=5ft
